【问题描述】：
我有一个在 Kubernetes 集群上运行的具有 3 个排序节点的网络。我正在使用 NFS 进行持久性存储。 Kubernetes 集群在裸机上运行。我将一个新组织加入网络，将该组织添加到联盟中。一旦我执行了命令peer channel create，订购者就开始抛出下面提到的错误：

自动重启后开始报错：

我相信第一个错误被抛出是因为 NFS 客户端创建了一个模式为 .nfsxxxxxxx 的文件。但我不明白第二个错误，我正在寻找解决方法。
我还在寻找用于裸机集群的 NFS 服务器的其他最佳存储机制替代方案。
任何建议/反馈将不胜感激
更新：其他 2 个订购者运行良好。
【问题讨论】：
-
我记得在与您相同的情况下遇到过类似的错误（Fabric with Kubernetes）。问题是在 orderer 复制过程中出现了多个 genesis-blocks（这意味着......多个版本），并且通过复制另一个运行良好的 orderer 的数据（块、文件）来解决。
-
@myeongkilkim 是的，由于多个创世区块，我看到了同样的错误。但在我的情况下，它之前运行良好，我只是在将组织添加到联盟中后才得到错误
